Schedule *Do Not Disturb* ======================= Just to add that you can also schedule Do Not Disturb from the command line to activate/deactivate each day at set times. To set the time when DND will be *enabled*: defaults -currentHost write ~/Library/Preferences/ByHost/com.apple.notificationcenterui dndStart -integer <start_time_in_minutes> To set the time when DND will be *disabled*: defaults -currentHost write ~/Library/Preferences/ByHost/com.apple.notificationcenterui dndEnd -integer <end_time_in_minutes> ***NOTE:*** replace `<start_time_in_minutes>` and `<end_time_in_minutes>` with the desired value (explained below). ---------- Example: -------- To schedule DND to start each day at 15:00 and to end at 18:30 do the following: Convert 15:00 and 18:30 to minutes to get the value of `<start_time_in_minutes>` and `<end_time_in_minutes>`. That is, multiply the number of hours by 60 and add the number of minutes. For 15:00 that would be: `15 * 60 + 0 = 900` and for 18:30 that would be: `18 * 60 + 30 = 1110`. Giving us the commands below: defaults -currentHost write ~/Library/Preferences/ByHost/com.apple.notificationcenterui dndStart -integer 900 defaults -currentHost write ~/Library/Preferences/ByHost/com.apple.notificationcenterui dndEnd -integer 1110 killall NotificationCenter # 'resets' Notificatio Center so that it reads the DND change
